ning of the automobile engine.

Another object of the invention .isto provide an advertising device withsign bearing members pivoted about a central axis so that with therotation of the sign bearing members at their pivots around the centralaxis the outer portions of the sign bearing members will be momentarilystopped by the. engagement with a spring member to exhibit a face ofthesign bearing member, after which thesign bearing members will be movedbeyond the spring to be engaged by a catch when the other ace of the.sign bearing member is exhibited.

Another object of the invention is to provide two discs each havingorifices spaced apart, there being a plurality of sign bearing memberseach having a rod disposed in the orifices in the discs, the rods beingheld normally in operative position by means which permit the removal ofthe rods with the sign bearing members when desired.

Another object of the invention is to provide means for rotating thesign bearing I --'Fi re *2 is an enlarge discs by means of a motor andadditional means for rotating the sign bearing discs manually whichpermits of the adjustment and replacement of the sign bearing memberswhich are mounted on the discs and without the running of the motor.

Other objects of the invention are to provide means for mounting the si11 bear- -ing bodies-on the rods and to provi e means for mountingadvertisin si ns on the si bearing bodies. g gn Additional objects ofthe invention will appear in the specification in which the preferredform of my invention is described.

In the drawings similar reference characters refer to similar parts inall the views of which Figure 1 is a sectional elevation illustrating myadvertisin device, transverse sectiona view of Figure 1,

' Fi re 3 is an enlarged sectional view on the line Figure 1,

Figure 4 is an enlarged sectional view on the line 4-4, Fi re 1, 1

Figure 5 is a view showing one of the sign bearing members Figure 6 is atragmentary sectional view illustrating the manner in which the signbearing memberggnay be removed from the device, and T 1 Figure 7 is asectional view showing a taxicab on which my advertising device ismounted.

By referrin to the drawings it will be seen that a cyhndrical casing 10is provided having a bracket 11 which is secured to the taxicab, asillustrated in Figure 7. This cylindrical casing 10 has a section 12which is covered by any desired transparent material so that theadvertising signs in the cylindrical casing may be exhibited topassengers riding in the taxicab. One side 13 of the cylindrical casing10 has a bearing 14 in which is-journaled a bearin member 15, thisbearing member 15 extending in the motor casing 16 to be driven by themotor contained therein.

' Secured for rotating with the bearing member 15 there is a disc 17,the disc 17 being separated from the-bearing member 15 preferabl by aplate 18. However, the disc 17 with t e plate 18 rotate with the bearingmember 15 and are held together for rotation by means of the pins 19.

In, the disc 17 there is a plurality of orifices 20 which are spacedapart adjacent the periphery of the said disc. Through the to by meansof which the rod 21 may be ro-' tated. The disc 17 is keyed to the'saidrod 21 and s aced from the said disc 17 there is a second isc 28 whichis also mounted on the rod 21 and which is keyed thereto.

This second disc 28 is also provided with a plurality of orifices 29adjacent its periphery and at the outer side of the second disc 28 thereis disposed a plate 30 which 1s mounted on the rod 21, and which isnormally held in engagement with the disc 28 by means of the stud 23.This stud 23 has a central opening 31 in which is disposed a sprin 32which presses at all times agalnst the p ate 30. It will thereforebe'seen that when the stud 23 is moved away from the late 30, the plate30 may be moved away om the disc 28 against the action of the spring 32.p

A plurality of sign bearing members is provided, one of these signbearing members being illustrated in Fig. 5 of the drawings. Each ofthese sign'bearing members has a body 33, one edge 34 of which is bentaround a rod 35 to clamp the sign bearing body 33 to the said rod 35.Preferably at the central portion of the edge 34 of the sign bearingbody 33 thesign bearing body 33 is cut away at 36 and at this cut-awayportion there is wound around the rod 35 a spring 37 ,the spring 37having two terminals 38, one disposed against each side of the signbearing body 33 to assist in holding against the si bearing body'anadvertisin member. brtions of the edge 34 of t e sign bearin body arealso extended at 39 to engage tfie faces of the sign bearing body 33 toassist in holding in position advertising members on the advertisingbearing body.

The rod 35 has extending terminals 40 and these terminals are normallydisposed in the orifices 20 and 29 in the discs 17 and 28.

However, when it is desired to remove one of the sign bearing membersfrom the device this is possible by unscrewing the stud 23, after whichthe plate 30 may be moved away from the disc 28, when the sign bearingmembers 23 may be moved to the position shown in Fig. 6 of the drawings,permitting their removal from the advertising device.

Of course, similar members maybe inserted in the device in the samemanner.

Figure 3 illustrates themanner in which the advertising members 41 aresecured to the sides of the advertising body member 33.

As has been stated, the motorin the easing 16 will rotate thebearingmember 15 andby the means described the twodiscs 17 and 28. With therotation of these discs the sign bearing'members 33 will move'in thedirection of the arrow, as illustrated in Figure 2 of the drawings,there being a sprin 43 secured to the upper part of the cylin ricalcasing 10 which will momentarily check the rotary movement of the signbearing members 33 to exhibit one face of each of the sign bearingmembers through the transparent portion 12 of the cylindrical casing.

However, with the continued rotation of the discsthe sign bearing memberwhich has been engaged by the spring 43 will be moved beyond the spring43 and will be caught by a clip 44 at the bottom of the cylmdncal casing10. This clip 44 has two arms 45 and 46, the sign bearing members fallng against the arm 46 of the clip 44, passing over the arm 46 and ridingon the arm 45 until with the continued rotation of the discs the signbearing member will be moved to the rear of the said arm 45, all ofwhich is illustrated in Fig. 2 of the drawings. A spring 44 l S pI0Vld6dto hold the clip 44 yieldingly in operative position.

While any desired motor means may be used to rotate the motor in thecasing 16 I prefer to use a suction motor, (not s own) which isconnected by means of the tube 47 bers'are preferably turned up to formsign retaining lugs 33. Any desired lighting means may be provided suchas the lamp 46.
